[0040] Example 2

[0041] like Figure 1-5 As shown, two countersunk holes 21 are provided on the same side of the end surface of the body 2 and the end surface of the lead cover plate 4 .

[0042] The base 3 is designed as an inverted "T"-shaped structure, which is compatible with the bottom end surface structure of the stator 1, and further supports the stator 1. A threaded mounting hole 31 is opened at the top of the base 3 corresponding to the inner hole of the stator 1, and the bottom periphery of the pull rod 5 is provided with an external thread and the threaded mounting hole 31 is connected with the thread, so that the pull rod passes through the stator 1 and is inserted into the base 3. It can be locked by simply inserting and twisting. When disassembling, it only needs to be completed by twisting and lifting, so that quick disassembly and assembly can be achieved.

[0043] The lead wire cover plate 4 is designed as a "T"-shaped structure, which is adapted to the upper end surface structure of the stator 1. Access holes 41 for inserting the adaptor pull rod 5 are provided through the inner holes of the stator 1 at both end surfaces of the lead wire cover plate 4.

During installation, the lead position can be positioned by aligning the notch with the two countersunk holes 21.

[0045] A wire outlet groove 43 is formed on the periphery of the wire lead cover plate 4 for leading out the cables of the stator 1 .

[0046] The pull rod 5 is composed of two sections. The part extending from the access hole 41 of the lead cover plate 4 is the upper pull rod 5, and the part inserted into the access hole 41 is the lower pull rod 5. The diameter of the upper pull rod 5 is larger than that of the lower pull rod 5, and the upper pull rod 5 and the lower pull rod 5 are integrally formed.

[0049] The installation steps of this utility model are as follows:

[0050] Step 1: After the pull rod 5 passes through the access hole 41 of the lead cover plate 4, the screw 52 is locked in the threaded limit hole 51 to support the lead cover plate 4, and then the upper pull rod 5 is used to limit the top of the lead cover plate 4 and then assembled with the pull rod 5. The stator 1 is placed on the base 3, positioned with the inner hole of the stator 1, and the pull rod and the lead cover plate 4 are installed into the stator 1.

[0052] Step 3: Install the stator 1 into the body and wait for 1-2 minutes to allow the stator 1 to expand and tighten the body 2. Then lift the pull rod 5 slightly upwards to allow the base 3 to clamp the inner hole of the stator 1. At the same time, loosen the pull rod 5, take the pull rod 5 and the lead cover 4 out from above the stator 1, and then move the body 2 to the cooling area.
